Operating System/Logic Control
The on-board operating system includes measurement, process-
ing, and output instructions for programming the datalogger. The
programming language, CRBASIC, uses a BASIC-like syntax. Measure-
ment instructions specic to bridge congurations, voltage outputs,
thermocouples, and pulse/frequency signals are included. Process-
ing instructions support algebraic, statistical, and transcendental
functions for on-site processing. Output instructions process data
over time and control external devices. These instructions include
averages, maximums, minimums, standard deviation, histograms,
rainow histograms, level crossings, and FFTs.
Above are measurement and control devices that are typically used with the CR9000X.
Enclosure Options
8253 Fiberglass Environmental Enclosure
The environmental enclosure is designed for eld applications where the
enclosure will be exposed to the elements. A CR9000X housed in this en-
closure is protected from water, dust, and most environmental pollutants.
8255 Lab Enclosure
The Lab Enclosure is for applications where the CR9000X will reside
inside a building.
Data Storage and Retrieval
Data storage and retrieval options commonly used with the
CR9000X series include:
PCMCIA Cards or CompactFlash® (CF) Cards can be used to
augment the datalogger’s storage capacity or to transport data or
programs from the datalogger to a PC.
Ethernet Cables connected to the on-board 10baseT/100baseT
port transmit data to a PC with an Ethernet port via a local net-
work or the Internet.
PC or laptop can be connected directly to the datalogger’s
RS-232 port (no interface required). This port provides electrical
isolation. Alternatively, the PC or laptop can be connected to the
CR9000X’s CS I/O port via an SC32B or SC-USB interface.
Although the following peripherals do not support the maximum
measurement rate, the CR9000X series is also compatible with:
Telephone modems (landline and cellular)
Spread spectrum radio
Measurement and Control Peripherals
The following peripherals expand the capabilities of the CR9000X series:
AM25T Multiplexer increases the number of thermocouples/
voltages that can be measured. Combinations of both can be
made on each AM25T.
SDM-CAN Interface allows the datalogger to sample data di-
rectly from a CANbus network.
SDM-INT8 Eight Channel Interval Timer expands the number
of pulse channels in the system and outputs period, pulse width,
frequency, counts, and interval time.
SDM-SIO4 Serial Input/Output Module provides four congu-
rable serial RS-232 ports for connectingour GPS sensor or other
devices that transfer data in a serial manner.
Although the following peripherals do not support the maximum
measurement rate, the CR9000X series is also compatible with:
SDM-CD16AC 16-Channel AC/DC Relay Controller
SDM-CVO4 4-Channel Current/Voltage Output Module
AM16/32B Multiplexer
